Opioid addiction is a serious public health concern with severe health and social implications; therefore, extensive therapeutic efforts are required to keep users drug free. The two main pharmacological interventions, in the treatment of addiction, involve management with methadone an mu (μ)-opioid agonist and treatment with naltrexone, μ-opioid, kappa (κ)-opioid and delta (δ)-opioid antagonist. MET and NAL are believed to help individuals to derive maximum benefit from treatment and undergo a full recovery...

PURPOSE: Recent controversies on the safety profiles of opioids and paracetamol (acetaminophen) have led to changes in clinical guidance on osteoarthritis (OA) management. We studied the existing association between the use of different OA drug therapies and the risk for acute coronary events. METHODS: A cohort of patients with clinically diagnosed OA (according to ICD-10 codes) was identified in the SIDIAP database. Within the cohort, cases with incident acute coronary events (acute myocardial infarction or unstable angina) between 2008 and 2012 were identified using ICD-10 codes and data from hospital admission...

Smokers keep smoking despite knowing that tobacco claims many lives, including their own and others'. What makes it hard for them to quit smoking nonetheless? Tobacco companies insist that smokers choose to smoke, according to their right to self-determination. Moreover, they insist that with motivation and willpower to quit smoking, smokers can easily stop smoking. Against this backdrop, this paper aims to discuss the addictive disease called tobacco use disorder, with an assessment of the addictiveness of tobacco and the reasons why smoking cessation is challenging, based on neuroscientific research...

INTRODUCTION: Epidural analgesia provides an important synergistic method of pain control. In addition to reducing perioperative opioid consumption, the deliverance of analgesia into the epidural space, effectively creating a sympathetic blockade, has a multitude of additional potential benefits, from decreasing the incidence of postoperative delirium to reducing the development of persistent postsurgical pain (PPSP). Prior studies have also identified a correlation between the use of epidural analgesia and improved oncological outcomes and survival...

Background: Chronic pain reportedly exerts complex effects on immune function. Natural killer (NK) cells are lymphocytes that play a critical role in cellular and innate immunity. This study examined changes in the subset populations and cytotoxic activity of peripheral blood NK cells in patients with chronic pain. Methods: Thirty patients with chronic moderate-to-severe pain (group P) and age-matched pain-free subjects (group NoP) were enrolled. Peripheral whole blood was analyzed for the percentage and expression of NK cell surface markers (CD56 and CD16) by flow cytometry...

Phlorotannins, phenolic compounds produced exclusively by seaweeds, have been reported to possess various pharmacological properties. However, there have been few works on these compounds from Mediterranean seaweeds. In this study, we investigated the phytochemical analysis and pharmacological potential of phlorotannin-rich fractions from three brown seaweeds collected along the Tunisia coast: Cystoseira sedoides (PHT-SED), Cladostephus spongeosis (PHT-CLAD), and Padina pavonica (PHT-PAD). Phytochemical determinations showed considerable differences in total phenolic content (TPC) and phlorotannin content (PHT)...

An important subgroup of people who inject drugs (PWID) receiving opioid agonist therapy (OAT), cannot be treated in the setting of a hepatology center and would not regularly ingest their medication when handed to them for self-administration. Our hypothesis was that chronic hepatitis C in these patients could be ideally managed if modern, interferon-free regimens were administered together with OAT under direct observation of a physician or nurse at a low-threshold facility. In this open-label, non-interventional, proof-of-concept study (ClinicalTrials...

G-protein-coupled receptors play a crucial role in various signaling pathways and function as targets for treating a wide spectrum of diseases. Since the 20th century, extensive research has been conducted on the Mu opioid receptor (MOR) as a drug target. We examined the MOR inactivation and activation processes by using an enhanced sampling method (Gaussian accelerated molecular dynamics), the binding pocket site area method, the root-mean-square deviation method, and the free energy (potential of mean force) method...

Chitra Garg, Sangeeta Khanna, Yatin Mehta
Abdominal field blocks are commonly used as part of multimodal analgesia for post-operative pain relief in patients undergoing abdominal surgery. Conventionally, transversus abdominis plane block is used, but has the disadvantage of limited spread only to T10-T12 segments, providing only partial pain relief. The new quadratus lumborum (QL) block has the advantage of providing wider sensory block from T6 to L1 and thus has an evolving role in opioid-free anaesthesia. Opioid-induced cough depression, urinary retention, and drowsiness can be problematic in patients with Prune belly syndrome, who have deficient abdominal muscles and myriad of genitourinary problems...

Aggressive resection of intracranial gliomas has a positive impact on patients' prognosis, but is associated with a risk of neurological complications. For preservation of brain functions and avoidance of major postoperative morbidity various methods of intraoperative neurophysiological monitoring have been introduced into clinical practice. At present, somatosensory evoked potentials (SSEP), motor evoked potentials (MEP), visual evoked potentials (VEP), brainstem auditory evoked potentials (BAEP), and electrocorticography (ECoG) are used routinely during neurosurgical procedures...

Richa Wardhan, Jacques Chelly
In this review, we discuss advances in acute pain management, including the recent report of the joint American Pain Society and American Academy of Pain Medicine task force on the classification of acute pain, the role of psychosocial factors, multimodal pain management, new non-opioid therapy, and the effect of the "opioid epidemic". In this regard, we propose that a fundamental principle in acute pain management is identifying patients who are most at risk and providing an "opioid free anesthesia and postoperative analgesia"...

BACKGROUND: Nociceptin/Orphanin FQ (N/OFQ), the endogenous peptide agonist for the opioid receptor-like (ORL1) receptor (also known as NOP or the nociceptin receptor), has been shown to block the acquisition and expression of ethanol-induced conditioned place preference (CPP). Here, we report the characterization of a novel small-molecule NOP ligand AT-312 (1-(1-((cis)-4-isopropylcyclohexyl)piperidin-4-yl)-1H-indol-2-yl)methanol) in receptor binding and GTPγS functional assays in vitro...

BACKGROUND & AIMS: Acetaminophen overdose is the leading cause of acute liver injury (ALI) and acute liver failure (ALF) in the developed world. Sex differences in acetaminophen-induced hepatotoxicity have not been described. METHODS: We collected data from the Acute Liver Failure Study Group cohort, a national registry of 32 academic medical centers in North America of adults with ALI or ALF, including 1162 patients with acetaminophen-induced ALI (n=250) or acetaminophen-induced ALF (n=912) from January 2000 through September 2016...

BACKGROUND: Total pancreatectomy (TP) is offered as a last treatment option for pain relief in patients with chronic pancreatitis. Concurrent islets autotransplantation (TP-IAT) may improve glucose control. METHODS: We analyzed results in 20 recent patients who underwent TP-IAT at The University of Chicago. The median observation period was 28 months (2-38). Data were collected prospectively then analyzed retrospectively. RESULTS: The number of patients requiring opioids daily for pain control decreased from 16 (80%) prior to surgery to 2 (13%) 1 year after, with only 1 (6...

The μ opioid receptor (OR), a member of the class A subfamily of G-protein coupled receptors (GPCRs), is a major target for the treatment of pain. G-protein biased μ-OR agonists promise to be developed as analgesics. Thus, TRV130, the first representative μ-OR ligand with G-protein bias, has entered into phase III clinical trials. To identify the detailed G-protein-biased activation and inactivation mechanisms of the μ-OR, we constructed five μ-OR systems that were in complexes with the G-protein-biased agonists TRV130 and BU72, the antagonists β-FNA and naltrexone, as well as the free receptor...

BACKGROUND: In Switzerland, intravenous drug use accounts for the majority of hepatitis C virus (HCV) infections. Early HCV treatment prevents further transmissions and reduces morbidity and mortality due to decompensated liver cirrhosis and hepatocellular carcinoma. Nevertheless, patients in drug substitution programmes are often insufficiently screened and treated. AIM: The aim was to compare the current state of HCV management in centralised and decentralised drug substitution programmes of the canton Aargau...
